Answer 2

$\Huge \fbox{Question}$

A rectangular lawn 100m long and 70m broad has two crossroads running in the middle of it - one 2m wide running parallel to its length and the other 5m wide running parallel to its breadth. Find the area of the lawn not covered by the crossroad.

$\Huge \fbox{Answer}$

Given::

• Length of rectangular lawn=100m
• Breadth of rectangular lawn=70m
• Breadth of road parallel to its length=2m
• Breadth of road parallel to its breadth=5m

To find::

• Area of lawn not covered by road.

Formula required::

• $\fbox{Area of rectangle=length×breadth}$
• $\fbox{Area of road=length×breadth}$

According to Question::

${ \dashrightarrow \sf{Area \: of \: rectangle=length \times breadth}}$

${ \dashrightarrow \sf{Area \: of \: rectangle=100m \times 70m}}$

${ \dashrightarrow \sf{Area \: of \: rectangle=7,000 {m}^{2} }}$

${ \dashrightarrow \sf{Area \: of \: road_{(parallel \: to \: length)}=length×breadth}}$

${ \dashrightarrow \sf{Area \: of \: road_{(parallel \: to \: length)}=100m×2m}}$

${ \dashrightarrow \sf{Area \: of \: road_{(parallel \: to \: length)}=200 {m}^{2} }}$

${ \dashrightarrow \sf{Area \: of \: road_{(parallel \: to \: breadth)}=length×breadth}}$

${ \dashrightarrow \sf{Area \: of \: road_{(parallel \: to \: breadth)}=70m×5m}}$

${ \dashrightarrow \sf{Area \: of \: road_{(parallel \: to \: breadth)}=350 {m}^{2} }}$

${ \mapsto\sf{Total \: area \:covered \: by \: road=(200 {m}^{2} +350 {m}^{2} )-(5m×2m)}}$

${ \mapsto\sf{Total \: area \: covered \:by \: road=650 {m}^{2} -10 {m}^{2} }}$

${ \mapsto\sf{Total \: area \: covered \: by \: road=640 {m}^{2} }}$

${ \mapsto\sf{Total \: area \: dosen't\: covered \: by \: road=Total \: area \: of \: lawn-Area \: covered \: by \: road}}$

${ \mapsto\sf{Total \: area \: dosen't\: covered \: by \: road=7,000 {m}^{2} - 640 {m}^{2} }}$

${ \mapsto\sf{Total \: area \: dosen't\: covered \: by \: road=6,360{m}^{2} }}$
